The Kalyspo unified system relies on two patent-pending components to prevent the vast majority of retained foreign objects (RFOs): the uTag and the Kalyspo Computer Aided Detection (CAD) software.

The uTag is a passive, x-ray visible, micromachined tag that greatly enhances the visibility of RFOs on radiographs (x-rays). It has an unmistakable shape that does not change in the human body. It produces a similar projection on x-rays regardless of orientation in space. Its size, geometry and materials are optimized to provide the optimal visibility on x-rays while remaining small and unobtrusive to the surgeon.

The Kalyspo CAD uses sophisticated image processing and detection algorithms weighed with a trained neural network to reliably detect the uTag. It can also detect other x-ray visible objects, such as needles, which comprise a third of RFOs and are too small to tag.
